Value Collection KP45134 Hex Head Cap Screw 3/4-16 Grade 8

Product Description

The VALUE COLLECTION KP45134 is a 3/4-16 UNF hex head cap screw designed for high-strength fastening applications. Manufactured from Grade 8 steel with a zinc-plated finish, it measures 2.75 inches under the head and features partial threading along the shank. The zinc coating provides baseline corrosion resistance for general shop, industrial, and mechanical assembly environments. This fastener meets ASTM A354 BD standards, making it appropriate for structural and load-bearing connections where a verified tensile strength rating is required. Sold in a pack of 25, it suits maintenance crews, contractors, and fabrication shops with recurring fastener demand.

This cap screw is suited for mechanical assemblies, equipment mounting, and structural connections that require a fine-thread UNF profile for precise torque control and vibration resistance. The partial threading allows the unthreaded shank to bear shear loads, which is common in bolted joint configurations across industrial machinery, HVAC equipment frames, pump housings, and general fabrication work. It is installed with a standard hex wrench or socket drive.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high tensile strength requirements
• 3/4-16 UNF fine-thread profile provides increased thread engagement and vibration resistance over coarse-thread equivalents
• Partial threading allows unthreaded shank to handle shear loads in bolted assemblies
• Zinc-plated finish adds corrosion resistance for indoor and sheltered outdoor applications
• 2.75 inch length under head accommodates standard stack-up thicknesses in mechanical assemblies
• Sold as a 25-piece pack for shop stock and repeat-use applications

Compatibility

Designed as a standard 3/4-16 UNF hex head cap screw for use in any application requiring a Grade 8 partially threaded fastener with ASTM A354 BD compliance.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with fastener torque requirements for Grade 8 hardware. Always consult the equipment manufacturer's specifications for proper torque values before tightening. Ensure mating threads are clean and free of debris before assembly. Do not use impact tools at full power to seat the fastener, as this can damage threads or exceed joint preload limits.
